Introduction
Strawberries (Fragaria x ananassa Duch.) are unique, with highly desirable taste, l avour, rich in vitamins, potassium, i ber and other secondary metabolites, also simple sugar source of energy, consumed as fresh table fruit or used in processing industry for jam and mar-malades or frozen (Wang and Galletta, 2002; Perez et al., 1997).
Strawberries are grown throughout the world. Although the yield/plant, size and colour of the common cultivars obtained in California are quite satisfactory, the local cultivars or types are in very big demand for their aroma and l avour (Üstün, 1996). h e new octa-ploid strawberry cultivars are high yielding and early fruiting, but poor in aroma constituents.
Numerous breeding programs aimed at improv-ing strawberry taste were done accordimprov-ing to demand (Hancock, 1999). h e main aspects of those breeding pro-grams were three major components of fruit organolep-tic quality: l avour, sweetness, and acidity. Consumers prefer sweet strawberries and sweetness is positively correlated with soluble solid contents (SSC), total solu-ble sugars, and fructose (Shaw, 1990). Many studies have addressed strawberry sweetness and acidity. Fruit solu-ble solids, titratasolu-ble acidity, and organic acids at matu-rity are quantitatively inherited (Shaw, 1997) Consumer preference is important in determining the value of new cultivars. For this purpose, a strawberry breeding program was initiated at the University of Çukurova, Faculty of Agriculture, Department of Horticulture in 1984 (Paydaş et al., 1996). In our country mostly farm-ers grow “Camarosa” due to yield, large fruits, and l esh i rmness that is highly desirable. But it is always condemn by the consumers due to of l avour and taste. Our local cultivar Osmanli is very rich in aroma and taste whereas its average fruit size is very small (roughly 5-8 g), l esh i rmness is highly undesirable due to its sot ness that renders it unsuitable for transportation. For these rea-sons we aim to develop more aromatic and tasty straw-berry genotypes in our country. h is breeding program has the major objective to develop new strawberry vari-eties especially well adapted and able to provide a high productive and qualitative standard.
In this paper, we aimed to evaluate adaptation per-formance especially average yield/plant, fruit weight and some phenological plant characteristics such as plant growth shape, plant density, plant vigour, leaf size, leaf sot ness, begining of l owering time and responce to Fe chlorosis of our local cultivar, promising hybrids from our and Italian breeding programs and some American and European cultivars.
Materials and methods
h is study was conducted in 2003-2004 and 2004-2005 growing periods in Experimental and Implementation Research Area and Laboratories of Horticulture Department in Faculty of Agriculture, University of Cukurova in Mediterranean region of Turkey. In the experiment, our local cultivar “Osmanlı”, American and European cultivars “Camarosa”, “Sweet Charlie”, “Gaviota”, “Maya”, “Paros”, “Cilady”, “Cigoulette”, “Marlate”, “Sophie”, “Ciloe”, “Diamante” and “Camarosa”, hybrids from Italian breeding program: “92/340/3”, “MT/ j24/2”, “MT99/20/1”, “MT99/121/9”, “MT99/163/14”, “MT99/163/19” and “MT99/163/22” and hybrids from Turkish breeding program: “3”, “5”, “6”, “8”, “11”, “13” and “17” were used as plant material. h e experiment was designed as a complete randomized block with three replicate; Twenty plants were used in each replicate. Black plastic mulch and drip fertigation system were applied. Average yield per plant (g/plant), fruit weight (g) and some phenological observations such as growth shape, plant density, plant vigour, leaf size, leaf sot ness, begin-ning of l owering time and response to Fe chlorosis of those strawberry genotypes in the i eld were examined. Phenological characters were done using modii ed de-scriptors of Faedi et al.(2002), and Paydaş et al. (1996).

Cilady was found to be very close to “Sweet Charlie”. In terms of this trait, Itailan hybrid number 92/340/3 was shown to be intermediate.
Average yield per plant per month and total yield per plant for genotypes in the experiment during the 2004-2005 growing period are given in Table 2. h e dif erences among the experimental genotypes in terms of average yield/plant/months and total yield/plant were found to be statistically signii cant and the lowest yield was obtained in March. In this month, the highest yield was obtained from hybrid number MT 99/163/22 (114.01 g) and the lowest yield/plant was obtained from hybrid number 17 (10.21 g) while no fruits were harvested from Osmanlı. h e highest yield was obtained in April, almost from all genotypes. In this month yield/plant varied from 34.60 g (“Osmanlı”) 193.38 g (“MT J24/2”). In May the lowest yield/plant was from hybrid number 5 (36.58 g) whereas the highest yield/plant was obtained from MT 99/163/19 (243.77 g). In June no fruits were harvested from hy-brids 13 and 17; whereas in this month the yield/plant increased in some genotypes such as hybrids 92/340/3, MT 99/163/14, and MT 99/163/22 and cultivar Paros. According to the obtained data the highest yield was ob-tained from hybrid number MT J24/2 (575.70 g) where-as the lowest yield wwhere-as obtained from cultivar Osmanlı (93.65 g). Turkish hybrid 6 was found to be very close to our hybrids and among the European cultivars culti-var Ciloe (375.37g) was found to be very close to hybrid number MT J24/2.
Similar results were obtained in terms of yield/plant of cultivar Camarosa and cultivar Osmanlı with Çağlar and Paydaş (2002) and Kak as (2004). However, Kak as (2004) reported that the results of yield/plant of hybrids (3, 5, 6, 8, 11, 12 and 13) were found to be higher than these experimental results. h e reason for this may be due to the dif erences in climatic conditions of experi-mental years. Due to the fact that Kak as studied the yield and other characteristics during 2001-2002 grow-ing period and in this period the winter was very mild in comparison to the our growing period. In addition, in this study we planted the fresh runner plants of ex-perimental genotypes approximately one month later then Kak as (2004).
h e average fruit weight of experimental genotypes and distribution according to the months are given in Table 3. As shown in Table 3 the average fruit weight was varied from 4.86 g (hybrid 12) to 15.77 g (92/340/3) in March. In the following month these values varied from 2.92 g (Osmanlı) to 17.34 g (92/340/3). In May, av-erage fruit weight increased almost in all genotypes in comparison to April. In June, the average fruit weight of experimental genotypes decreased in comparison
to the previous month. As a result, the highest average fruit weight was obtained from hybrid 92/340/3 (12.99 g) whereas the lowest value was obtained from cultivar Osmanlı.
Average fruit weight of experimental genotypes and distribution according to the months during 2004-2005 growing period are given in Table 4. h e dif erences among the genotypes were found to be statistically signii -cant in all months. In March, average fruit weight varied from 4.86 g (hybrid number 12) to 15.77 g (92/340/3). h e fruits of hybrid number 17 and cultivar Paros were found to be very close to 92/340/3. Average fruit weight of experimental genotypes were decreased in hybrid numbers 3, 6, 11, 13, 17 and cultivars Camarosa, Sweet Charlie, Marlate, Cilady, Gaviota, Cigoulette, Paros, Maya and Diamante while increased in others. Average fruit weight was increased in May almost for all geno-types whereas in July decreased. h e highest average fruit weight of experimental genotypes was obtained from hybrid number 92/340/3 (12.99 g) while the lowest one was detected as cultivar Osmanlı. Ilgın et al., (2002) reported similar results in terms of average fruit weight for cultivar Sweet Charlie. Our results were found to be lower than that of Kak as (2004) in terms of average fruit weight of hybrids 3, 5, 6, 8, 11, 12, 13 and 17.

Conclusion
In this paper, performance of our local, European and American cultivars and cultivar candidates from our and Italian breeding programmes were compared. As a result, hybrids MT J24/2 and MT 99/163/22 were found to be very satisfactory in average yield/plant and fruit weight, respectively. Hybrid number 8 from our breeding program was observed the earliest one, while MT J24/2 from Italian breeding program the latest one. Cultivar Cilady and hybrids 6, MT 99/121/9 and MT J24/2 were observed as the ones with highest resistance to chlorosis which caused Fe dei ciency.
